What is License Express?
License Express is an online system for managing prorate and fuel tax accounts. It replaced the Taxpayer Access Point System (TAP) in March 2025. When it launched, an email was sent to those with existing TAP accounts with directions on moving their account to License Express. If you had an account in the TAP system, you must transfer it to License Express.
